Application filed January 18, 1909. Serial No. 472,896.

To all whom it may concern:

Be it known that I, J onN K. Puunnnronn, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Vehicle- Lamps; and I do here y declare the following, when taken in connection with the accompanying drawings, and the numerals of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-- Figure 1 a front view of a lamp constructed in accordance with my invention showing a screen interposed between the burner and the reflector. Fig. 2 a sectional view of the same and also illustrating means for reducing the light. screen shown in the preceding figures in the closed position. Fi 4 a sectional view showin the inside i one of the walls'of the tube. ig. 5 a si e view of one of. the intermediate fan leaves, detached. Fig. 6 a sectional view at right angles to that shown in Fig. '3.

This invention relates to an improvement in vehicle lain s, and particularly to those of the search-light character used in automobiles, motor boats, etc.

It is a well known fact that when two vehicles are approaching each other, the headlight and search-1i ht of one vehicle so blinds the eyes of the driver of the other vehicle that it is impossible for either to see any obstructions which may be in their path.,

The object of this invention is to temporarily suppress the action or the reflector by inter-posing a device between the burner-and the reflector, and the invention consists in the construction as hereinafter described and particularly recited in the claims.

The objects of this invention may beaccomplishedin a variety of ways. .Thus means may be. arranged between the burner and the reflector to temporaril suppress the action ofthe reflector. As 0 early shown in Figs. 1 and 2 of the drawings, this device may be in the form of a fan comprising swinging leaves 2, more or less in number, arran ed in front and rear of a vertically movable eat 3 which is connected to the upper end of a ver- Fig. 3 a sectional view of the the reflector 8'. It will be noted that the tube is arranged in line with the burner, and preferably and as shown, corresponds substantially in diameter to the diameter of the tube, or at least is no wider than the tube so that no additional shadow is cast by it.- In order to spread the fan the front and rear walls of the. upper end of the tube are formed with cam surfaces 9, and the outer leaves formed with studs 10 to coact therewith. This outer leaf carries a pin 11 which enters a' slot 12 formed in the next leaf, and

vehicles are a proaching each'other, if the rod 4 be raiser to open the fan between the light and the reflector, the action of the refiector is suppressed. The burner, however, is not affecte and the light therefrom will be sufficient to enable one driver to see the course of the other. As soon as the vehicles pass it is only necessary to reverse the movement to draw the fan into the tube.

It will he" understood that by the term burner as used herein, I wish to be under stood as including a gas-burner, oil burner, or electric light. I claim:-

1. In a lamflp, thecombination with a burner and re act or, of'a tube located between the burner and reflector and in line with said burner, a vertically movable rod in said tube, and fan-like leaves connected with said rod and adapted to be projected and spread above said top of said tube. 2. In a lam the combination with a burner and re ector, of a tube located between the burner and reflector in line with and corresponding in diameter to the diameter of the burner, a vertically movable rod in said tube, and fan-leaves connected with said rod and adapted to be projected and spread above the to )of said tube.

3. In a 1am the combination with a burner and re ector, of a tube located bemovable rod in said tube, and fen-leaves con: nected with said rod and adapted to be projeoted and spread above the top of said tube.

4. In a 1am the combination with a burner and re cctor, of a tube located be tween the burner and reflector, a i'orl in sairl tulle, a central leaf connected with said rod, e series of leaves connected with said central leaf, cam-surfaces in said tube, pins in the outer leaves ada ted to en 'age with said cam surfaces, an pin and slot connections between the leaves whereby when the central leaf is raised, the other leaves will be spread above the tube.

5. In a lamo, the combination with a burner and reflector, of e tubecloeatecl be In testimony whereof, l have signed. this specification in the presence of two subscribing witnesses.
